Specification of Letters Patent. Patented J 111163118, 1918.

Application filed November 26, 19 17. SerialN 0. 204,065.

To all whom it may concern:

Be it known that I, JACOB BOLANDER, of the city of Toronto, in thecounty of York, in the Province of Ontario, in the Dominion of Canada,have invented certain new and useful Improvements in Bag-Holders, and dohereby declare that the following is a full, clear, and exactdescription of same.

This invention relates to adjustable devices for the supporting of bagsin an open condition to facilitate the filling of such bags,beingparticularly adaptable for such purposes as mail-sorting,grain-bagging and like purposes, and having as an object ,to provide areadily-operable and adjustable device of simple construction which willeffect the supporting of a bag in a very secure manner, wherebyliability of the said bag to slip, or he accidentally displaced, fromthe support will be materially obviated; an important object also beingto arrange resilient gripping members in such relation tobag-supportingarms, with which they cooperate, that the pressure of the said grippingmembers may be concentrated at certain desirable points, upon a bagbeing supported by the device, to secure great efficiency in the saidgripping operationtogether with certain other advantages which will behereinafter pointed out. 1

Further objects subsidiary to or resulting from the above-mentioned mainobjects, or from the construction of the invention as it may be carriedinto effect, will become apparent as the invention is hereinafterfurther disclosed.

In carryingmy said invention into effect Imay provide, as an example,the novel construction and arrangement of parts whereby a frame or headis, preferably, slidably arranged and vertically adjustable upon avertical support, said frame having hinged thereto, and disposed upon:either side thereof, a pair of outwardly-extending bag-supporting armswhich may swing upon their hinges, over respective quadrants formingpart of the base of said frame, one or both of which quadrants .may beprovided with teeth with which suitable interlocking means, carried bythe arm or arms, may detachably engage to determine the adjustment ofthe said arms with. respect to one another; and it is preferred that alink connection should beprovided between, and co-acting" with, the saidarms whereby angular adjustment-of one of thesaid arms will beaccompanied bvthe synchronous adjustment of the other of said arms, butin, an opposite direction thereto, as will be readily understood. Theouter parts of the arms, thatis, the parts which are intended toactually'engage with the bag, are preferably somewhat raised above theplane of theinner parts of the'said arms in proxim1ty to the quadrants,whereby the rim of the bag may be folded thereoverso that the body ofthe bagv will depend between the arms, and gripping members secured tothe said .arms adjacent to said quadrants and adapted to swingvertically out of operative position, may be arranged in such mannerthat, when in their securing posi-' tion, the outer ends of thesaidgripping members are secured in contact with that part of a bagcontiguous to' the outer ends of the supporting arms by suitable 8801111 ing means, such as clips, against resilience:

in the said members, the said members also impinging upon the said bagat points substantially removed from the extremities of the said arms,whereby the resilient forces, in the said arms, areconcentrated at thesepoints, and also clearance provided between, the gripping members andthe supporting arms, intermediate of the said points of resilientcontact therebetween and the points of contact at the extremitiesthereof, all off which is more particularly described {and ascertainedhereinafter, having reference to the example illustrated in theaccompanying drawings, in which:

Figure 1 is a perspective view I of the arms, grippers and the same,

a hopper shown which may be used in con- 7 nection therewith wheredesirable.

Similar characters of reference indicate similar parts in the severalfigures of the drawings.

1 is a vertical support and 2 a frame or head vertically adjustable onthe said support 1, adapted tobe locked in any such vertically-adjustedposition by means of the thumb screw 3, the form of frame shown in thedrawings being characterized by quadrants 2 and 2*, one of which isserrated or toothed near its periphery, a pair of radial hinge housings2 and .2 and. a pivotlugQfi extending upwardly from the base of saidframe intermediate of the said quadrants 2 and :2". Hingedly mounted onpins at and 5 respectively through the hinge housings 2 and 2 areoutwardly extending arms 6 and 7 hereinafter called the bagsupportingarms, vertically ofi'set intermediate of their length, whereby shoulders6 and? are provided, and preferably substantially oflset laterally inproximity to the said shoulders,

as will be readily understood from an examination of Fig. 2 of thedrawings, that is to say, the said bag-supporting arms have each alateral S bend therein whereby the distance between the said arms issubstantially increased intermediate of their length. It will be seenthat the said bag-supporting arms 6 and 7 are capable of swinging overthe quadrants 2 and 2 respectively, and in order to synchronize themovement of the said arms toward or away from one another, a linkconnection therebetween' may be provided comprising a pivoted lever 8mounted intermediate of its length upon the pivot lug 2 already referredto, and having one end connected by a link 9 to the arm 6 and the otherend by a further link 10 to the arm" 7. The said lever 8 is preferablypivoted at a point somewhat nearer the end carryin'g the innermost link10 in order to secure an equal movement of the two arms.

It will be seen that the arms, as constructed, permit abag to besupported there-between while the rim of the bag may be folded thereoverto engage with the said arms in the manner as particularly indicated inFig. 3 of the drawings, so that if a bag be so supported by the saidarms and the arms be; distended as far as the rim of the bag willpermit, then an appreciable downward force in the body of the bag wouldbe required to remove the same from the said supporting arms, due to thebinding efi'ect of the folded rim thereon.

In order to insure a very efficient gripping of the" bag upon the arms,grippers 11 and 12 are provided, in the form of resilient metal stripshinged at 13 and 14 to the inner parts of the said arms 6 and 7respectively, the outer ends off-he said grippers having clips 15 and16- mounted thereon to engage with the outer ends of the saidbag-supporting arms, when the grippers 11 and 12 are brought intooperative position. It will be seen from an examination of Fig. 2 of thedrawings that the laterally offset part of each arm passessomewhatbeyond a plane between the hinge 0f the respective gripper andthe end of the arm, with which the clip carried by the said gripperengages, so that, when bringing the clips into engagement with the arms,the said grippers will first contact intermediate of their length withthe laterally ofi'set parts (forming stops for said grippers) of thesaid arms, whereby the completion of the closing of the grippers againstthe arms must be effected against the lateral resilience of the saidgrippers; and the arms may be so shaped that when the grippers are sosecured in their operative position, clearance is provided, between thegrippers and the respective arms, intermediate of the said points ofresilient contact therebetween and the points of contact at theextremities thereof, these features being all illustrated in the saidFig. 2. The hinged natureof the grippers permits them to-be swungupwardly so that they do not interfere with the adjusting of the rim ofthe bag upon the gripper arms prior to bringing the said grippers intooperation.

In Fig. 3 of the drawings a hopper l7 is shown which may be veryconveniently used with the device described, said hopper being carriedby a ring 18 revolubly mounted, upon the support 1, whereby the hoppermay be swung out of position during the adjustment of the arms andgrippers.

By the use of this invention, a bag may be supported in such manner thatthe frictional resistance, due to the folding of the rim thereof oversupporting members, is employed, to effect the securing of the bagagainst displacement, in combination with the concentration of resilientforce at certain desirable points, together with thesecuring, by clips,of the bag at the extremities of the supporting members; and therelative arrangement of the arms and their respective grippers, wherebyclearance is provided th'erebetween throughout part of their length,while contributing to the concentration of forces already described,also permits bags having heavy seams therein to be used with the devicewithout lossof'eflt ciency so far as the mechanical operation of thedevice is concerned.

This invention may be developed within the scope of the following claimsWithout departing from the essential features of the said invention, andit is desired that the specification and drawings be read as beingmerely illustrative and not in a limiting sense, except as required bythe prior art.

What I claim as my invention is:

1. In a bag holder, a pair of bag-supporting arms provided with upwardlyofi'se't portions over which the rim of a bag may be folded, gripperssecured at their inner ends to said arms, said grippers, when operative,extending along the outer surfaces of the upwardly offset portions ofsaid arms, and

locking means carried at the free ends of the grippers to engage thearms.

2. In a bag holder, a pair of bag-support ing arms provided withupwardly offset portions over which the rim of a bag may be folded, andgrippers hingedly secured at their inner ends to said arms, the outerends of said grippers bemg'adapted to en age the upwardly extendingofiset portions of said arms to bind the folded rim of the bag thereon.

3. In a bag holder, a laterally ofiset bagsupporting arm, a laterallyelongated gripper secured at one end to said arm, and

' means to detachably secure the free end of said gripper to said arm,whereby when the gripper is attached at both ends to the arm theintermediate portion thereof will impinge against the lateral oflset inthe arm and the closing of said gripper is eifeoted against theresilience thereof.

4. In a bag holder, a bag supporting arm,

gr pper interme iate of its length, Whensaid ripper is partly closed onsaid arm, wherefiy the full closing of said gripper Will be effectedagainst the resilience thereof.
